摘要
这篇论文在幂定律液体在连续移动表面上为界面层流动论述热转移的理论分析。有不同的热传导性系数的热界面层厚度的表情根据液体动力学和热转移的维的分析的理论被获得。并且 CFD 的数字结果与建议表情同意很好。估计公式能成功地被用于给热界面层厚度。
This paper presents a theoretical analysis of the heat transfer for the boundary layer flow on a continuous moving surface in power law fluid. The expressions of the thermal boundary layer thickness with the different heat conductivity coefficients are obtained according to the theory of the dimensional analysis of fluid dynamics and heat transfer. And the numerical results of CFD agree well with the proposed expressions. The estimate formulas can be successfully applied to giving the thermal boundary layer thickness.
